According to an affidavit to get an arrest warrant, Baker was invited by the child’s mother, who was an acquaintance of his, to another child’s birthday party at a house belonging to the mother’s neighbor.

The party, which was attended by 10 or 12 children, plus numerous adults, began Saturday afternoon and continued into Saturday night, the child’s mother told police. She said after 10 p.m. or 10:30 p.m., when the party began breaking up, she didn’t see her child or Baker, and returned to her apartment to search for them.

The mother said she found her daughter crying and screaming that Baker was trying to kill her and had put his fingers down her throat, police said. The mother said she saw blood on the inside of her daughter’s thighs as well, police said.

Putnam police responded to a report of an assault shortly after 1 a.m. Sunday. The child was immediately taken by ambulance to Day Kimball Hospital and later moved to the Connecticut Children’s Medical Center.

An examination of the child showed indications that she had been assaulted, including sexually, police said.

Police found Baker in Day Kimball’s parking lot, talked to him at the station and arrested him around 3 a.m.

Putnam Police Detective Bart Ramos, who prepared the arrest warrant affidavit, said that while he was interviewing Baker, he noticed numerous small cuts and scratches on his hands and wrists that could have been caused by the girl during a struggle.

Baker denied to police that he had done anything wrong to the child.

Baker’s criminal record includes an October 2009 conviction for fourth-degree sexual assault of a minor. He received a suspended sentence and five years’ probation and was required to register as a sex offender.

The terms of Baker’s probation also include requiring him to have no contact with children.

Baker faces charges of two counts of risk of injury to a minor, first-degree strangulation, threatening, first-degree kidnapping and two counts of first-degree sexual assault. He is held on $500,000 bail.
